Abstract

A LED reflector manufacturing method including the steps of i) preparing an injection molding material by mixing about 70% of polycarbonate+about 10% PBT+about 20% titanium dioxide+about 0.012% carbon powder mixture, which is obtained from one part of carbon powder with 50 parts of talc powder, to result in 100% of the injection molding material; and ii) injection-molding the injection molding material into desired reflectors at about 260° C.±15° C.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A LED reflector manufacturing method including the steps of: i) preparing an injection molding material by mixing about 70% of polycarbonate+about 10% PBT+about 20% titanium dioxide+about 0.012% carbon powder mixture, which is obtained from one part of carbon powder with 50 parts of talc powder said mix resulting in 100% of the injection molding material; and   ii) injection-molding the injection molding material into desired LED reflectors at about 260° C.±15° C.   
     
     
       2. The LED reflector manufacturing method of claim 1 wherein the desired reflectors are injection-molded from the injection molding material at 270° C.
